BURNER ATTACHMENT.

SPECIFICATION formingpart of Letters Patent No. 709,278, dated September 16, 1902.

Application filed July 24, 1901. Serial No. 69,536. (No model.)

To all whom it may concern:

Beit known that we, THOMAS L. Her and THOMAS MARSHALL, J r., citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Burner Attachments, (OaseNo. 1,) of which the followingisafull, clear, concise, and exact description, reference being bad to the accompanying drawings, forming a part of this specification.

Our invention relates to burner attachments,.and is particularly adapted for use in heating. curling-irons.

Our object is to devise a burner that will be very compact in form and which will permit of the ordinary use to which a gas-jet may be adapted and which will be adapted to serve in its own capacity by a slight adjustment.

In practicing our invention we provide a slight aperture in the jet-tube of the main burner and surround this jet-tube with a ring that carries the supplemental-burner tube, the bore of the supplemental-burner tube having communication with the bore of the ring. The ring is rotatable, so as to bring the bore of the supplemental-burner tube into communication with the aperture in the mainburnertube. Whenthesupplementalburner is not to be used, a slight rotation of the ring will cut off the gas supplied thereto, where upon the main burner is restored to its normal condition,so that it may be used or thrown out of service, as desired. We preferably employ a stopper to close the outlet of the mainburner tube, the stopper being preferably composed of hard rubber, the lava tip being removed each time the stopper is inserted. This insures the proper flow of the gas through the supplemental-burner tube. The supplemental-burner tube preferably has a section added thereto and placed above the same in axial alinement therewith, which is separated by an air-space, so that a thorough mixture of air and gas is effected to produce perfect combustion, resulting in a Bunsen flame, which speedily heats the iron. The support for the curling-iron or other instrument that is to be heated is preferably carried by the ring surrounding the main-burner tube.

We will explain our invention more fully by reference to the accompanying drawings, in which Figure 1 is a side elevation of one of many well-known types of gas-fixtures to which the invention may be applied, the device of the invention beingillustratedin position. Fig. 2 is a vertical sectional view through the main and supplemental burner tubes and parts im mediately associated therewith. Fig. 3 is a front elevation of the device of the invention, the curling-iron being in position to be heated by the flame of the supplemental burner.

Like parts are indicated by similar characters of reference throughout the different figures.

We have illustrated one of many well-known types of gas-fixtures, thatillustrated being in the form of a bracket a, provided with a gascock 1) near the wall from which the bracket projects, and a main-burner tube 0, within which a lava tip d is normally inserted, this lava tip being shown displaced to illustrate the application of the invention. The mainburner tube is provided with a circular apertu re or perforation e, communicating with the main bore of the tube. The portion or zone of the main-burner tube where the said orifice is located is surrounded by a ring J, from which projects a supplemental-burner tube 9. The bore of the supplemental-burner tube is continued through the ring, the ring being so located that when rotated thesupplementalburner tube will be brought into communication with the bore of the main tube through the aperture 6. To effect the rotation of the ring f, we preferably provide the same with a knob 7t. To properly guide the ring f in its motion, we preferably provide the same at its lower edge with a slot 71, engaging a pin is, projecting from the main-burner tube. When the pin is engaged with one end of the slot, communication between the supplementalburner tube and the main-burner tube is out 01f. When in engagement with the other end of the slot, this communication is established. To properly seal the aperture 6 by the ring f, the said ring is preferably made-of softmetal as, for example, an alloy composed of eighty parts, by weight, of lead, ten parts of tin, and ten parts of antimony. The ring f is a slipring, whereby it may be readily slipped over the main burner. By the term slip-ring or slip-support is meant one that does not have threaded engagement. While the gas is passing through the supplemental-burner tube the main-burner tube is preferably closed at its upper end, though it is no tabsolutely necessary to close it. For this purpose the lava tip (1 is preferably removed, whereupon a stopper is", composed, preferably, of hard rubber, is inserted in its place. The tip and stopper are preferably attached to the ring by means of cordsor chains Z Z, that may be connected to the knob h. The supplementalburner tube projects in adownward direction, being provided with a short vertical stretch where the outlet occurs. To secure perfect combustion, we prefer to place over the supplemental tube 9 an additional tubular section m, a space being provided between the tubular portions 9 and m to permit of the mixture of air with the gas. The support for this section m of the supplemental-burner tube may be in the form of an arm n, provided at its ends with spring-clips 0 and 19, that engage the ringf and the tube-section m, respectively, an enlargement in the tubesection engaging the clip 19 to hold the said tube-section the proper distance above the tube g.

The support for the curling-iron or other tool q is preferably'in the form of a fork whose membersr r are engaged with the ring f, a collar 0", attached to the base of the fork, slipping over said ring for this purpose. The fork projects upwardly and slants a trifle, so that its ends are placed in the same lane with the supplemental-burner tube. Vghere the fork is to support curling-irons, one of the members 1" thereof is provided with a ring 8, through which the curling-iron is passed, while the companion member of the fork'is provided with a trough t to engage the points of the curling-iron.

We have herein shown and particularly described the preferred embodiment of our invention; but it is obvious that changes may be made without departing from the spirit thereof, and we do not, therefore, wish to be limited to the precise disclosure herein set forth; but,

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. The combination with a tube provided with a perforation in its wall to afford communication with its bore, of a ring surrounding the portion of the tube where the said perforation is located, and a burner-tube secured to the ring, the bore of the said tube continuing through the ring and adapted to be brought into and out of communication with the said perforation by the rotation of the said ring, substantially as described.
